Dog Anal Gland Disease: Prevention and Treatment

Anal gland problems are among the most common reasons dogs visit vets, causing significant discomfort, and understanding causes and prevention can reduce chronic suffering in affected dogs.

Key Facts

Dogs have two anal glands (sacs) that normally empty during defecation via two ducts opening beside the anus
Signs of impaction include scooting, excessive licking of the rear, and a fishy odour
Anal sac impaction progresses to infection and abscess if untreated; abscesses are extremely painful
Small breed dogs including Chihuahuas, Toy Poodles, and Cocker Spaniels are overrepresented
Dietary fibre supplementation increases stool bulk and improves natural anal gland expression
Chronic anal sac disease may require surgical removal (anal sacculectomy) as a permanent solution

Welfare Considerations

Anal gland impaction causes persistent discomfort and pruritis around the anus, leading to scooting behaviour that many owners find troubling but that represents the dog's attempt to relieve pain. Progression to abscess causes severe acute pain and systemic infection. Many dogs suffer for weeks before owners recognise the problem as a medical issue rather than a behavioural one. Regular veterinary monitoring of anal glands in at-risk breeds, dietary management to improve stool bulk, and prompt treatment of early impaction dramatically reduce the welfare burden of this highly manageable condition. Dogs should never be left to scoot indefinitely without veterinary assessment.

What You Can Do

If your dog is scooting or excessively licking its rear, seek veterinary assessment promptly rather than assuming it is behavioural
Ask your vet about dietary fibre supplementation if your dog has recurrent anal gland impaction
Request demonstration of how to check for anal gland fullness at home for at-risk dogs
Consider surgical removal (anal sacculectomy) if your dog has chronic recurring impaction or infection despite dietary management
